Attic ventilation baffles are an important part of any healthy home. They help to ensure that air can circulate freely throughout the attic, which prevents moisture buildup and heat build-up. Baffles also help to keep insulation from blocking soffit vents, which can reduce the effectiveness of your attic ventilation system.
If you don’t have attic baffles, or if your baffles are old or damaged, you can make your own baffles out of a variety of materials. This is a relatively simple project that can be completed in a few hours.
Benefits of Attic Ventilation Baffles
There are many benefits to having attic ventilation baffles, including:
- Reduced energy bills: Baffles help to keep your attic cool in the summer and warm in the winter, which can reduce your energy bills.
- Improved air quality: Baffles help to remove moisture and other pollutants from the air in your attic, which can improve the air quality in your home.
- Reduced risk of mould growth: Baffles help to prevent mould growth in your attic by keeping the air dry and moving.
- Extended lifespan of your roof: Baffles help to reduce the risk of moisture damage to your roof, which can extend the lifespan of your roof.
Materials and Tools Needed
To make your own attic ventilation baffles, you will need the following materials and tools:
- Rigid foam board (1/2-inch thick)
- Aluminum foil tape
- Utility knife
- Staple gun
- Measuring tape
- Safety glasses
- Measure the distance between the rafters in your attic. This will be the width of your baffles.
- Cut the rigid foam board into strips that are the same width as the distance between the rafters.
- Cut the rigid foam board into lengths that are equal to the depth of your attic.
- Apply aluminium foil tape to all of the seams of the rigid foam board. This will help to seal the baffles and prevent air from leaking out.
- Position the baffles between the rafters, so that they create a clear channel for air to flow from the soffit vents to the ridge vent.
- Staple the baffles into place. Be sure to staple the baffles to the rafters, not to the insulation.
- Repeat steps 5 and 6 until all of the baffles are installed.
- Be sure to leave a 1/2-inch gap between the top of the baffle and the roof sheathing. This will allow for proper airflow.
- If you have any gaps between the baffles and the rafters, seal them with aluminium foil tape.
- If you have any insulation that is blocking the soffit vents, remove it.
- If you have any questions or concerns about installing attic ventilation baffles, consult with a qualified roofing contractor.
- Baffle type: There are two main types of attic ventilation baffles: rafter vents and soffit vents. Rafter vents are installed between the rafters, while soffit vents are installed in the soffits of your roof.
- Baffle material: Attic ventilation baffles can be made from a variety of materials, including foam board, plastic, and metal. Foam board baffles are the most common type of baffle, as they are relatively inexpensive and easy to install.
- Baffle size: Attic ventilation baffles should be the same width as the distance between the rafters in your attic. The depth of the baffles should be equal to the depth of your attic.
- Baffle installation: Attic ventilation baffles should be installed so that they create a clear channel for air to flow from the soffit vents to the ridge vent. Be sure to staple the baffles into place, and seal any gaps between the baffles and the rafters with aluminum foil tape.
Making your own attic ventilation baffles is a relatively simple and inexpensive project that can have a big impact on the energy efficiency and comfort of your home. If you don’t have attic baffles, or if your baffles are old or damaged, I encourage you to make your own baffles today.
